Cisco Firewall :: Getting ASA5520 Total Configuration Dump?
Oct 9, 2011
We have a pair of ASA5520 firewalls setup in a very inefficient fashion, and I wish to convert them to an active/passive cluster. Trouble is, there are a number of configuration option I will need to re-implement (VPN tunnels, remote users etc), and trying to capture the configuation with a simple "show running-config" or "show running-config all" or even "show startup-config" doesn't get me things like the pre-shared-key from the VPN configurations - and I don't know them all, so I can't simply re-enter them.Is there any way to get a dump of the running (or startup) config which shows the hidden settings like pre-shared keys and OSPF message digest keys?
I'm trying to establish a very basic connection (ping) between 2 laptops, one sat on the outside interface, and one on the inside as per the diagram below:
I can ping back and forth from the ASA to 192.168.1.4, and to 10.1.1.1. However, what I'm trying to achieve is to be able to ping from 10.1.1.1 to 192.168.1.4 and vice versa.
I have attached the configuration file with this post as well.
We received an ASA5520-K8 through Cisco's Loan program so we could demo it as a replacement for our aging Cisco 3005 VPN appliances. Given that we are a non Cisco shop (except for specific appliances like concentrators and wireless access points), I don't have a great deal of experience with Cisco gear.I started to set to setup the appliance this morning but immediately ran into issues. The 5520 doesnt seem to be acting as a DHCP server, and worse yet, I can't access the unit even if I hard code the IP on the PC being used for configuration. I have to say that I feel kinda stupid having to post this, since I actually followed the documentation avaiable for this menial task and I fully expect the problem to be a simple one. Namely, I am using two specific sources of info for connections.
I am forced to upgrade my ASA 5520 software from 7.1 - 8.2 or higher, as I am not familiar with ASA I need expert opinions.I have following concerns regarding the upgrade.
1-Do I need to worry about the software licensing when I download 8.2
2-I read about the few difference in commands (ACL and NAT) in 8.2 what exactly I have to do here should I change the configured NAT and ACL with real IP in the existing configuration after the upgrade ?
I am in the process of migrating my config from my PIX running 8.0(4) to my ASA5520 running 8.2(1). I have converted the config so that it is ready for the ASA. I noticed the "boot system flash:" and "asdm image flash:" command references the old PIX files. Do I need to update these or will they be updated when the ASA reboots with the new config?
I have a problem with RME 4.2 from CWLMS 3.1. I have configured SSH in my asa 5520 device but RME can't get the configuration file. I ran a job to sync archive but i get this message error:
*** Device Details for ASA_5520_VOZ_01 *** Protocol ==> Unknown / Not Applicable Selected Protocols with order ==> Telnet,TFTP,SSH Execution Result: CM0062 Polling ASA_5520_VOZ_01 for changes to configuration. CM00 Polling not supported on
i hav asa5520 i copying configuration from PIX to ASA5520 (7.2) everything working fine bt problem is that after sometime my DMZ interface losing connectivity ...
I am going to migrate an ASA5520 with another one having VPN configuration+certificates etc. I am a bit concern about the certificates. Shall I need a new certificate because of new IP addresses on the new ASA ? Should I configure the same IP in order to avoid this. There are many VPN clients with public keys that also need to change. Is there any way for minimal changes for migration ?
I have problem with one AIR-LAP1252AG-N-K9 AP. When i am connecting the laptop through wifi to this AP i am getting blue dump. If the same laptop connect to any other ap i haven't get any error. Laptop Model no is Lenovo L412.
AP Has below IOS version.c1250-k9w8-mx.124-21a.JA2
I upgraded the firmware to latest and apparently i've lost couple of options inlcuding TCP Dump in diagnostic as well as I cannot find how to disable/enable an ethernet port.
7200 VXR router got rebooted after due software crash dump.I have replaced NPE-G1 but still router is rebooting. Currently I am running with 12.4 (15)T 13 IOS.Crash Dump file is attached.
I am running two ASA 5520 routers synched up with eachother. I had a massive connectivity issue this weekend that I am investigating. Now I have figured out how to get the live logging but I need to know how to get the old logs from my router.Also I am looking to set up a log dump that could happen daily or perhaps weekly.
I used to use this forum all the time when i was younger and I pretty much learned most of what I knew about computers from this website (the rest I learned from breaking stuff and then having to fix it). I'm really excited to be back on this website and learning about computers again. The latest generation of consoles really pulled me away from playing my video games on computers and thus i no longer felt the need to over clock everything. Now, for my current problem:
I just recently purchased a linksys e3200 router and have been using it in place of my Belkin N600 (which i bricked ). The router is ran to my cable modem (which is located behind my TV) and the router itself is located about 6 feet away on top of my fire place mantle. The router is connected to my ps3 slim 250gb and my motorola sb6120 both with cat6 10 ft cables at 1gbps. I have a amd laptop with built in wireless g, and intel laptop with wireless g, a pc with a wireless g usb and a wii all connected to the router. Thus, the router stays in wireless g broadcast mode.
THE PROBLEM is that the router will work for about 30 seconds to 30 minutes and then it just starts crapping out. All the computers lose their wireless connection to it, and it would seem that sometimes an online game for ps3 gets bad packetloss during this dump. The only way to fix the problem is if i reset the router. A soft reset works for about two minutes, and if i do the 30-30-30 reset, it starts working again for another 30 min to an hour.
Here is what I already know:No known source of interference near the router.nly one other network in the area, and I have tried every available wireless channel.Have not only upgraded to latest version of cisco firmware, but now I am using mini- DD-WRT.Have tried increasing broadcast power on DD-WRT.Have played with the settings in DD-WRT pretty extensively after reading the guides on what settings do what.
The connection issues still happen even if my laptop is 3 feet direct line of sight from the router.It would seem that the problem happens with wired as well, just that it recovers so quickly on wired that most people wouldn't notice.
My cable modem typically averages between 20-30mbps down and 1-3 mpbs up (i moved to a small rural area that charges extortionate prices for better packages). I can't afford a wifi spectrum analyzer tool.
Here is the kicker for me: EVERYTHING worked flawlessly until one day it just quit working. Absolutely nothing was changed. Some of my computers are very far away and on a different floor in the house, so if I have to get another router it's not the end of the world because i can just put this one on repeater mode. I just don't understand how a rather well-received router model could have such bad issues.
Any ideas apart from the typical: location, firmware, interference, channel, channel width, reset ideas? Even now, the router works very well until it goes back on life support.
With regarding to the firewall ASA5520, i'm using it in my network, all the confiuration are properly configured and working but with the use of proxy address in internet explorer(e.:206.53.155.129/3128) all the blocked contents as easily accessible simply it bypass all the network through firewall.so will u guide me to block the proxy servers.
I have two asa 5520 firewalls. one at my primary data center connected to our production Internet feed, and one at my fail over data center connected to a backup internet feed. I was wondering if there was an easy way to keep the firewall rules in sync between the two firewalls. We have failover with our isp that will move our public facing address block from our primary site to our dr site in the event of a disaster so the ip addresses will not change if we were to have to fail over to the DR site. currently i just have to do any changes that i make on the fail over server but would like a way to at least simi-automat this if not fully automat this so that i can eliminate the possibility of human error of a change happening at primary but never getting don at DR.
I have a asa5520 with five Internet IP.One for the internet interface and the others are static maped to dmz hosts. It runs rightly until yesterday.Now it will lose the connection to the gateway many times everyday and the dmz hosts can not connect to internet any time. configuration(simplified):
! interface GigabitEthernet0/0 nameif internet security-level 0
[Code]....
I called ISP to check,when ISP clear their router's ARP, the asa will lose the connection at the same time and then the ISP's router couldn't learn the ASA's MAC. After I 'clear arp' manually,The ISP's router can learn the ASA's MAC and the connection recovered,but the DMZ's cann't access internet still (of course,There is no problem between DMZ and ASA ,I ping the internet gateway from DMZ host and can not get any reply.).
We have 2 x ASA5520 and I upgraded this to 8.2.2 last year, I see 8.2.5 and now 8.4 is out. If we are having no issues, is it best just to leave it as it is? I can see a couple of features I may find useful in 8.2.5, but 8.4 seems like a huge jump and a risky one too.
I am trying to introduce an ASA5520 to my network based on the following diagram: ISP Internet ------> ASA5520 ------- > Cisco Router ------> LAN. The problem is I cannot ping the ASA from the LAN. I can ping it from inside the router. I already allow ICMP within ASA. If i remove the cisco router and replace it by a swich, I can ping the ASA with NO problem.
We want to use ASA5520 but both Firewall have different CPU. One has CPU Pentium 4 2400 MHz and another has Pentium 4 Celeron 2000 MHz. Can it be configured for replica / failover?
We have 2 firewalls on PIX facing the Internet and connected to interface e1 (behind it) an ASA version 8.3 Both the PIX (Firewall facing) and the ASA are on the same subnet.
By using Routing statements and statics I have been able to reroute specific traffic to the ASA5520 version 8.3 Now I need to inverse the 2 devices. The ASA5520 will be facing the Internet and the PIX will be behind it.Unfortunately the ASA5520 is refusing to route the traffic to the PIX. The access-lists are open accordingly and a NAT on the ASA has been created.
i have my router connected to ISP then my router directly connected to my ASA5520....i use also ASA5520 as my DHCP Server and i was wondering with the DHCP Server function of ASA 5520 because if i use the ASA 5520 LAN ip ...all workstation will not be able to browse anything from the internet unless i use my ISP DNS IP which they gave me?
Get the following log message on secondary ASA console output when turning on the ASA failover function?
"Mate's service module (CSC SSM 6.6.1125.0) on slot 1 is different from mine (CSC SSM 6.6.1125.0)"
After that the secondary cannot join as a failover unit and shows in disabled status.We have the same model ASA & CSC module and each pair of them are in same firmware (CSC 6.6.1125.0 with ASA5520 8.4(4)1), when I shutdown both the csc modules, the ASA failover works fine.
I am using a squid proxy behind an ASA5520 firewall to collect the users to the internet. Squid is just necessary to log what is going on in order to find a quick solution when the internet slows down.
Considering that I have unlimited licenses and I would like to get rid of squid, I wonder if the ASA has some functionalities to track which websites are being used and how much traffic is generated. If there is not, I would like to know if Cisco offers a good product to replace Squid.
Upgraded an ASA5520 from 7.x to 8.4 in one step? Release notes for 8.4 state that you can "...upgrade from any previous release directly to 8.4..." I've read the previous version release notes and see the various changes in NAT etc that 8.3 made.
Any limits on the number of IPSec sessions an ASA5520 can support over a DSL connection?
Currently, as we increase the number of IPSec VPN tunnels, our LAN switches connected to the DSL/ASA start seeing CRC/input errors. Tried different LAN ports for both DSL/ASA connections - same reults (CRCs and errors). Swapped ASA for PC running 1 IPSEC w/HD video and no issues.
VPN connection bandwidth demand 50% of DSL capacity, so not exceeding DSL bandwidth. Errors get so bad that all VPN sessions drop - sometimes VPN sessions re-establish while other instances a DSL modem reboot is required.
cause of LAN switch connections seeing errors with 4+ VPN sessions established on ASA across a DSL Internet circuit?
I'm trying to configure an ASA 5520 with cut-through proxy feature. The user is required to be authenticated when trying to access an outside resource from the inside. This is a test lab before it is implemented in production. [code]
I have a pair of brand new 5520s I am in the middle of commission. After carving out all the DMZs etc I needed I realized that I really neede another physical NIC, not just another VLAN off a configured nic. [code]I am running 8.3(2). How can I turn these "Not used" interfaces into useable ones?
I have Cisco ASA5520 with a 8.4 code in GNS3. I have a problem pinging to the internet. On the ASA console, I can ping to outside world, but on vpc I cannot ping the outside world. But I can ping the ASA Inside interface and other VLANs, no problem. [code]
I have a question about access-lists on ASA: (5520 running 8.4)Often I want to permit all traffic from networks behind an interface (let's say DMZ in this example) to Internet, but NOT to internal networks. Then I first configure a Deny from DMZ to all internal network and then a Permit to ANY. If I forget the first Deny I will allow all traffic also to my internal networks. Is it possible to configure an access-list that permit all traffic from a network to all networks that are reachable via a given interface? In this example: Permit all traffic from DMZ to all networks that are reachable via the Outside-interface? This should permit traffic to Internet and deny traffic to internal networks in one statement.If I specify the outside-interface as the destination only traffic to the interface itself will be allowed.
